  • Click on the Execute Analysis ( ) icon to bring up the Execute Analysis wizard again.
  • Expand the Lifeline category and select Electric Power Utility Network Damage (Hazus Style). Click the Finish button.
  • In the analysis graph, click on the Electric Power Utility Network Damage (Hazus Style) icon to bring up the form page.
    1. For the Result Name field, specify a name such as Electric Power Network Damage for INA.
    2. For the Power Network field, click the Search ( ) button and find the dataset called Memphis Electric Power Network for INA and click the Finish button to add it to your scenario.
    3. For the Hazard field, click the Search ( ) button and locate the scenario earthquake we just created for the water network damage. If you used the example name previously specified, it should be called Memphis 7.3 Scenario Earthquake. Click the Finish button after you have located the dataset.
  • All other required fields should be filled in so you can now click the Execute button to run the analysis.

One stipulation should be noted here. Since our power network did not contain any nodes, there is no damage result that can be applied to the Interdependent Network Analysis. However, since it is a required input, we still needed to generate the result dataset. In the INA, the power network will be ignored and only the water network damage will be used to determine service reduction and connectivity lossthing to note here is that our network dataset inputs (e.g. Memphis Electric Power Network for INA) contain both a link and a node dataset; however, MAEviz can only display the links in the visualization view even though nodes are present as well. The drawback of this is that even though the Electric Power Utility Network Damage (Hazus Style) and the Water Utility Network Damage Analysis computed damage to both links and nodes, only the damage to the links can be displayed and viewed in the tabular view. The damage to the node dataset is there and will be used in the Interdependent Network Analysis even though they cannot be viewed. Now that we have our power network damage and water network damage, let's proceed to find what the effects are from their interdependencies.

    1. For the Water (or Gas) Connectivity Loss Result Name field, specify a name such as Water Network Connectivity Loss.
    2. For the Power Connectivity Loss Result Name field, specify a name such as Power Network Connectivity Loss.
    3. For the Water (or Gas) Service Flow Reduction Result Name field, specify a name such as Water Network Service Flow Reduction.
    4. For the Power Service Flow Reduction Result Name field, specify a name such as Power Network Service Flow Reduction.
    5. For the Water (or Gas) Utility Network Damage field, select the result we just created from the drop down menu. If you followed the tutorial explicitly, then you should have a dataset called Water Network Damage for INA, select it.
    6. For the Electric Power Utility Network Damage field, select the result we just created from the drop down menu. If you followed the tutorial explicitly, then you should have a dataset called Electric Power Network Damage for INA, select it.
    7. For the Network Interdependency Table field, click the Search ( ) button and find the dataset called INA - Memphis interdependency table, click the Finish button to add it to the scenario.
    8. For the Number of Simulation field, choose enough simulations to get a reasonable sampling. Something around 500 should be sufficient.
    9. Under the Advanced Parameters section, you can leave the Use Homogeneous Interconnectedness Level? box unchecked.
  • Click Execute to run the analysis.
